Unit Ultrasonic-I2C

SKU:U098-B1

Description

The Unit Ultrasonic-I2C is an ultrasonic distance measurement sensor with an I2C communication interface. The hardware utilizes the RCWL-9620 ultrasonic distance measurement chip paired with a 16 mm probe, enabling precise distance measurement within a range of 2 cm to 450 cm (with an accuracy of ±2%). As an I2C slave device, the sensor can share bus resources with other I2C devices, maximizing IO resource savings. It is ideal for applications such as robot obstacle avoidance and liquid level detection.

Note: When measuring distances greater than 3.5 meters, there may be a slight delay in the distance measurement response.
